The effects of overinflation of the lung in obstructive lung disease on the function of chest wall (rib cage, diaphragm) were studied. Concerning the function of the rib cage, the lateral motion of the lower lateral rib cage was evaluated using several experimental models. The results showed that the lower lateral rib cage was moved by many factors, including the force of the diaphragm, rib cage, compliance of abdominal wall, zone of apposition and angle of the diaphragm at the part of its insertion into the rib cage with respect to the transverse section of the trunk. The inward motion of the lower lateral rib cage due to overinflation of the lung occurred by participation of these factors. Concerning the function of the diaphragm, the diaphragm at high lung volume in healthy subjects and patients with pulmonary emphysema was evaluated by the three-dimensional stereoscopic method. The radius of the portion of the dome in the diaphragm decreased at higher lung volume, and changes in lung volume at that lung volume were caused by changes in the shape in the posterior of the diaphragm.
研究了阻塞性肺疾病中肺过度充气对胸壁（胸廓、膈肌）功能的影响。关于胸廓的功能，使用多种实验模型评估了下外侧胸廓的侧向运动。结果表明，下外侧胸廓受多种因素影响，包括膈肌的力量、胸廓、腹壁顺应性、附着区域以及膈肌在其插入胸廓部位相对于躯干横断面的角度。肺过度充气导致下外侧胸廓向内运动是这些因素共同作用的结果。关于膈肌的功能，采用三维立体方法评估了健康受试者和肺气肿患者高肺容积时的膈肌情况。膈肌穹窿部在高肺容积时半径减小，该肺容积下肺容积的变化是由膈肌后部形状改变引起的。
